Nd:YAG laser operate at which wavelength?

Explanation:
Nd:YAG lasers emit their primary light at 1064 nanometers, a near-infrared wavelength. This fundamental line is characteristic of neodymium-doped YAG crystals and allows deeper penetration into skin with relatively lower absorption by melanin, which is why it’s commonly used for hair removal across a range of skin types. Other wavelengths you might see in similar systems come from different laser types or from converting this light to other colors (for example, through frequency doubling to 532 nm), but the Nd:YAG’s standard operating wavelength is the 1064 nm line.
